ORY + O2 simms = knock???!!! help... ok, i just installed a Mac off road Y pipe with a pair of O2 simms and now i'm getting up to 3 degrees of KR. prior to the ORY, i never got any knock. at first i thought it was because my Y pipe was banging my driveshaft loop, but i fixed that tonight and i still have knock... 
any ideas? did this lean my car out? i have a Predator programmer so i can play around with it some. i may try putting some 95 octane in to see if it goes away... any other suggestions i should try? i always have a hard time reading my 02's on the predator while driving--they jump around so much anyway.

Re: ORY + O2 simms = knock???!!! help... your knock sensor is probably going bad...It gets real sensitive when it goes bad(and picks up every little noise)....theres also a knock desensitising mod you can do too it also...better just to buy the new one....they're not that expensive and If its a 99 its probably due anyways.
